Morphological study of one septal trabecula carnea of the left ventricle.
This work was carried out in 50 hearts of human adult cadavers of both sexes, whose obit causes were not related to diseases which could have been directly involved with the heart. The septal trabecula carnea was identified in 45 hearts (90%), with origin in the superior portion of the interventricular septum and the other extremity was sited in 33 cases (61.1%) in the base of the anterior papillary muscle. It was unique in 37 hearts (82.2%) and dissociated in 8 hearts (17.8%). The more frequent length and width was 40 mm and 3 mm, respectively.
